BLO'ITING APIELIANCE.

Application filed April 14, 1922. Serial No. 552,567.

To all whom it may concern Be it known that I, HENRY Ro'rrnNnURG, a subject of the King of Great Britain, and resident of 5 Adams Road, Cambridge, in the county of Cambridge, England, have invented certain new and useful Improvements in Blotting Appliances, for which I have filed an application in England dated August 30th, 1921, of which the following is a specification.

This invention relates to; blotting appliances of the type wherein one or more pieces of blotting paper are secured to a curved member so that this latter can be rocked or rolled over the writing to be blotted. It is the object of the invention to provide an appliance of this character which can be supported securely and comfortably on the back of the hand of a person engaged in writing, so that such person can blot the writing whenever required without putting down his pen, by turning over the hand and causing the blotting surface to bear with a rolling motion upon the ink writing to be blotted. A further object of the invention is to provide an adjustable securing device for a blotting appliance of this character whereby it can be adapted readily to fit any size of hand.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a front view, and

Figure 2 is a side view of the hand of a person engaged in writing, with the appliance in position.

Figure 3 is a perspective view of one form of the appliance drawn to a larger scale.

Figures 4, 5 and 6 are side views of various forms of the appliance.

In each form of the appliance there is a convex outer portion or plate a upon which sheets of blotting paper I) are supported in any convenient manner, as by spring clips 0, and a concave inner portion or plate 03 shaped to fit over the back of a hand; a looped band or tape 6 extends from a. point of attachment as at f on one end of the por tion d of the appliance which fits over the back of the hand, the said looped band being intended to embrace the thumb of the wearer as seen in Figures 1 and 2, while a tape or band 9 extends from the loop eback to the other end of the appliance. In Figures 3 and 4 a bar h with a serrated edge is shown extending across the appliance between the ends of the outer plate a and the inner plate all, while the band 9 which passes through a slot at sin the appliance, is attached at z to a slider 7s working on the bar it. The slider 70 has a spring catch [for engaging with the serrations on the bar it, this spring catch being releasedwhen required by pressing inwards the head m while holding the slider by the projection n, when the slider can be moved freely along'the barfor adjusting the free length of the band 9 or releasing the same to any required extent. The slider 76 may be moved toward the left hand end of the bar it in Figures 3 and 4 for example, when the appliance is being put upon the writing hand, in order to enable the hand to be passed freely into position 'with the thumb in the loop 'c;'the slider is then moved toward the right, the spring catch Z riding over the serrated edge of bar it, until the band 6, g, engages tightly enough with the hand to hold it firmly while still leaving the fingers and thumb tree to grip the pen 7? firmly for writing purposes, as in Figures 1 and 2. Whenever it is desired to blot the writing, the hand is turned over with a movement'of the forearm, while the pen is still held between the thumb and fingers and the blotting paper I) on the plate a is brought to rest upon the writing, the blotting being efiectcd with a rocking movement of the appliance as the forearm is turned.

The bar 72. need not be straight as in Figures 3 and 4, but may be curved as in Figure 5. Instead of the bar and slider, any other convenient means of adjustment of the band 9 may be employed. 7

In Figure 6, the band 9 is made of elastic material so that it requires no adjustment, but will expand to permit of the insertion of the hand and will contract again so as i to hold firmly upon it.

In Figures 3 and 4 the appliance is shown as having the parts a and 0! made of separate plates united by clamp joints at 0 and g respectively. where the ends of the bar h are also attached, the bar being secured at one end if required by a rivet 1", Figure 4a 7 The outer part a of the appliance can then be made of springy steel so as to allow it to become partially flattened by pressure, while the inner part (,2 may be of aluminium for example. In Figures 5 and 6 on the other hand, the parts a and d of the appliance are shown as being in one piece, formed for example from a tubular piece of metal by bending to the shape shown.

It will be understood that the body a, (Z of the appliance is not necessarilymade of metal, vbut may be formed of any suitable sufficiently rigid material, while the blotting securely upon the back thereof.

material 5 may be secured in any convenient manner, and any suitable form ofbandor strap may be used adapted to embrace or grip the hand so as to hold the appliance The appliancemust cc-light and easily applied and removed, while beingheld firmly in post tion during use so as not to impede the use of the hand for Writing and other purpose:-;, and the constructions illustrated may obviously be varied in several respects while still providing an appliance having these characteristics so as'to be well adapted for the purpose in view.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is 7 1. Ablotting appliance com-prising convex outer portion adapted to support blot-- ting material upon its surface, a concave inner portion adapted to fit upon the back of ahand, and means for securing said con cave inner portion upon the hand, said means comprising a band with a loop therein for embracing the thumb of the wearer.

2. A blotting appliance comprising a support for blotting material, said support having aconcavely shaped inner surface, and

means for securing said appliance with its concavely shaped inner surface bearing upon the back of a persons hand, said means comprising a looped band attached at one part to the appliance and adapted to embrace the wearers thumb, and a further length of band extending fromthe looped portion to another part of the appliance.

3. A blotting appliance comprising a support for blotting material, said support'ha'ving a conoavely shaped inner surface, and means for securing said appliance with its concavely shap d inner. surface bearing upon the back of a persons hand, said means comprising a band adapted to pass around the hand oft-he wearer, one part of said band-"being fixed to's'aid appliance,

a slider and means for supporting the same upon said appliance, means off-connection between said slider and" another part of said band, and means for adjustably positioning said slider wherebythe band may be released or tightened as occasion may require. v
